Larger species of greying elf found grazing in areas of dense literature. Believed to survive predominantly on crime novels, which it consumes leaving only traces of a brittle, crisp-like substance as evidence of its existence. Crispin-catching emerged as a popular pastime during the 1830's, but the practice is now obsolete. Historians have recently questioned the validity of crispin sightings, and indeed they are now generally regarded as mythical creatures by the majority of the populus, believed in only by crazed booksellers who have recently been Dowled.

"Quick carruthers! Fetch the rifle or indeed the dustpan and brush! I believe I have a crispin in my sights!"
